Osborn 0007568500 End Brush Stainless Steel Crimped Wire

Product Description

The OSBORN 0007568500 is a miniature end brush designed for rotary tool applications requiring precision cleaning, deburring, and surface preparation on delicate or hard-to-reach surfaces. Built with fine crimped stainless steel wire, this brush delivers consistent contact and extended service life in demanding shop and field environments. The 0.25-inch brush diameter makes it well-suited for working inside small bores, ports, and tight cavities. It runs at up to 25,000 RPM and includes a shank for direct chuck mounting. Machinists, maintenance technicians, and fabricators commonly use this type of brush for light-duty surface finishing and part cleaning tasks.

This end brush is used in applications where a small contact footprint and gentle abrasive action are required. Common scenarios include cleaning fuel injector bores, threaded ports, precision machined components, and small castings where coarser tooling would cause damage. The fine grade and crimped wire configuration allow the filaments to flex and conform to irregular surfaces without removing base material. It fits standard rotary tools, die grinders, and flex-shaft machines used in fabrication shops, maintenance facilities, and general industrial settings.

Key Features

• 0.25-inch brush diameter for access to tight bores and small openings
• Fine crimped stainless steel wire construction for long brush life and flexible contact
• Rated to 25,000 RPM for use with high-speed rotary tools and die grinders
• Shank included for direct mounting — no additional adapter required
• Fine grade fill suitable for cleaning delicate parts without aggressive material removal
• Not bridled, flared, piloted, or encapsulated — standard open-wire end brush configuration

Compatibility

Designed as an OEM-style replacement end brush compatible with standard rotary tools, die grinders, and flex-shaft machines that accept a shank-mounted end brush accessory.

Installation Notes

End brushes of this type are installed and serviced by machinists, maintenance technicians, and industrial fabricators. Before mounting, confirm the tool chuck and collet are sized to accept the brush shank. Always verify the tool RPM rating does not exceed the brush maximum of 25,000 RPM before operation. Wear appropriate eye protection when using rotary wire brushes, as wire filaments can shed during use.
